I posted this on the wrong forum so maybe I will get a better response on the correct one!

This icon has shown up on my phone beside the profile settings. I have tried turning on and off the boost through the media settings, pressing th L while on a call, and removing the battery all with no luck removing it. The other way to remove, or change it, is supposed to be through the menu function while on a call but my phone does not have an enhanced audio option from the menu while on a call.
